Boracite originated in Germany in the year 1789 and named after its boron content. It is a relatively rare mineral that forms in sedimentary and metamorphic environments.
Boracite can be found in a few locations worldwide such as Germany, Austria, Russia, and the United States.
Boracite occurs in evaporite deposits, which are formed by the evaporation of saline solutions. It often occurs as tabular or prismatic crystals within these deposits. Boracite can also be found in marine evaporites, salt beds, and borate-rich sediments.
Boracite is composed of high thermal stability and electrical insulating properties, making it useful in various industrial applications.
It is used as a fluxing agent in the production of boron compounds, as a filler in refractory materials, and as a component in ceramics and glass.
